ANATOMY

Detailed explanation-1: -After the fertilization, the cleavage of the embryo leads to the formation of the germinal disc. As food, the chicken egg yolk is a major source of vitamins and minerals. It contains all of the egg’s fat and cholesterol, and nearly half of the protein.

Detailed explanation-2: -The full-term human fetus develops from a single cell and needs nutrition from the moment of conception. The developing fetus relies primarily on the mother’s placenta for energy, but it takes nearly 12 weeks until growth of the placenta is complete.

Detailed explanation-3: -A yolk sac is a structure that develops inside your uterus during early pregnancy. It provides an embryo with nourishment (food). It helps circulate gasses between you and the embryo. The yolk sac also produces cells that turn into important structures, such as the umbilical cord, blood cells and reproductive organs.

Detailed explanation-4: -The egg yolk contains high amount of vitamin A, D, E, K, B1, B2, B5, B6, B9, and B12, while egg white possesses high amounts of vitamins B2, B3, and B5 but also significant amounts of vitamins B1, B6, B8, B9, and B12 (Table 2).

Detailed explanation-5: -Eggs contain a number of different types of fat which are present entirely within the yolk. They are naturally high in monounsaturated fats. These fats help maintain normal blood cholesterol levels. Eggs also offer polyunsaturated fats, including omega-3 fatty acids, which are needed for normal brain function.
